I suggest taking a look at the actual load weight specs on the tires you're thinking about getting. Multiply by 2 to get the axle total. Divide by the axle rating (3500 lbs for the mid size rpods, 4400 lbs for the bigger ones). That number should be around 1.25 to 1.5 or so, giving your tires a 25-50% safety factor. A low safety factor will increase the risk of tire failure, too high will increase stiffness too much and result in excessive shaking and vibration. 

And keep the tires inflated to specs, if they are underinflated they flex more and get hotter.  Trailer tires have thicker sidewalls than car or truck tires, so they dissipate heat more slowly, so they are more prone to failure if underinflated than car or truck tires. But, because they flex less they have less rolling resistance so you'll get better fuel economy. 

Many complaints about "Chinese tires" are really incorrect user maintenance resulting in underinflation, combined with marginally spec'd OEM tires to begin with

I like the idea of having the additional weight handling capability for more of a safety margin. 

We originally replaced our tires with Maxxiis 8008. Later, we found Goodyear Endurance.  We love the Endurance tires. they seem much stiffer so the trailer does not bounce as much.  They do not leak-I check the pressures frequently and seldom need to add any air. 

 a lot of podders like Carlisle.  I can't speak from personal experience.

whatever tires you get  is your choice.  However, in any event you should get them balanced. it makes a lot of difference. Agree with McCarter-get the load range D
